25mm Countersink 90° HSS 3-Flute Cylindrical Shank For Deburring And Countersinking Steel, Cast Metals, Non-Ferrous - TECWERK

Compact, efficient countersinking with proven DIN geometry: the combination of HSS cutting material, a 90° chamfer and a three‑flute design ensures clean chamfers and low vibration during machining. The tool is suited to steel, cast iron and non‑ferrous metals and provides a reliable feed behaviour (0.2 mm/rev at feed forces up to 500 N).

TECWERK 90° Countersink DIN 335 C, Ø25 mm, HSS, 3 flutes

A TECWERK 90° countersink DIN 335 C, Ø25 mm, HSS designed for fast, burr‑free countersinking and deburring of drilled holes in steel, cast iron and non‑ferrous metals

• HSS material for high wear resistance
• Three‑flute geometry for rattle‑free cutting
• 90° chamfer angle for standard countersinks

Precision chamfers with robust HSS construction

The countersink is manufactured in HSS, providing a good balance between toughness and wear resistance for general workshop use. The DIN 335 C designation denotes the standardized conical geometry, which guarantees consistent chamfer angles across production runs. With a nominal diameter of Ø25 mm and a cylindrical shank, the tool integrates easily into common collet systems and tool holders. The three‑flute layout reduces axial vibration and distributes cutting forces evenly, which contributes to a more consistent surface quality and reduced rework.

Stable cutting behaviour and measurable feed performance

Thanks to the three cutting edges, the tool delivers a rattle‑free cut, reducing chatter marks and improving finish on both the chamfer and the bore edge. The specified feed behaviour—0.2 mm/rev at feed forces up to 500 N in steel—provides a practical starting point for machining parameters; this measurable value helps when setting feeds on drilling machines or machining centres. Because the geometry and material are oriented towards general metalworking, the tool is suitable for both manual and automated countersinking tasks where repeatable chamfer quality is required.

Practical workshop benefits and application notes

Designed for countersinking and deburring of holes in steel, cast iron and non‑ferrous metals, the tool reduces secondary finishing steps and shortens cycle times by producing clean chamfers in a single pass. The cylindrical shank permits straightforward clamping in standard collets; for optimal results, use appropriate clamping and maintain recommended spindles speeds for the workpiece material. Regular inspection and cleaning of the flutes help preserve cutting performance and extend service life, keeping downtime to a minimum.

FAQ

What materials can be processed with this countersink?
The TECWERK 90° countersink is suitable for steel, cast iron and non‑ferrous metals, as stated in the product description.

What does DIN 335 C indicate for the countersink?
DIN 335 C specifies the standard conical geometry for countersinks; the TECWERK tool conforms to this geometry to ensure consistent 90° chamfers.

How many flutes does the tool have and what is the benefit?
This countersink features three flutes; the three‑flute design produces a rattle‑free cut, improving surface finish and reducing vibration during countersinking.

What feed rate is recommended for steel?
The documented feed behaviour for the tool is 0.2 mm/rev in steel at feed forces up to 500 N, which serves as a practical machining guideline.

Which shank type does the countersink use and how is it clamped?
The tool has a cylindrical shank, allowing clamping in standard collets and holders compatible with workshop equipment.
